improve upon the ordinary construction of the lay in a narrow-ware or ribbon loom.

In the ordinary construction of the lay in a narrow-ware or ribbon loom the lay consists of a heavy wooden beam supported upon and attached to the upper ends of two or more swinging lay-swords, according to the width of the loom. This wooden beam is recessed or grooved upon its upper surface to receive the reciprocating rack which moves the ro-.

tary pinions which communicate motion to the swivel-shuttles in the well-known way. In the ordinary narrow-ware or'ribbon loom the lay is of considerable length,varying from ten to twenty feet or more. the length of the lay and its required rigidity it has been necessary to use a solid wooden beam of considerable size, some five inches or more in thickness and in height. This wooden beam is liable to warp or get out of shape in the direction of its length, so that the longitudinally-moving rack carried thereon and having a sliding motion therein will not operate accurately and communicate accurate movement to the pinions which move the swivel-shuttles, and, further, in order to remove the pinion-operating rack from the beam for any purpose after the loom has been put together and into operation it is necessary to draw the rack out from one end of the beam. This requires a large amount of space and is not a convenient way of removing the rack, and, further, by reason of the height of the wooden beam forming the lay it has been necessary to have the hand-rail extend at a considerable height above the lay.

The object of my invention is to improve By reason of upon the ordinary construction of the lay above described.

In my improved construction of the lay I do away entirely with the wooden beam forrn ing the lay, as above described, and substitute therefor a metal bar of angle shape in crosssection. I thus obtain a greater rigidity of the lay and prevent its getting out of line. I combine with the angle metal bar a wooden bar, detachably secured thereto by screws or otherwise upon its front side and which has a longitudinal recess or groove therein to retures of construction of my improvements, as .will be hereinafter fully described.

I have only shown in the drawings detached portions of one end of a lay and a lay-sword embodying my improvements with some parts thereon suflicient to illustrate the nature of my invention.

. Referring to the drawings, Figure 1 is a front view of the right-hand end of the lay and the upper part of a lay-sword embodying my improvements and looking in the direction of arrow a, Fig. 2. Fig. 2 is a section on line 2 2', Fig. 1, looking in the direction of arrow 6, same figure. Fig. 3 corresponds to Fig. 1, but shows the'bar carrying the rack dropped down to allow of the removal of the rack and also shows an adjusting-screw for the rack. Fig. 4 is a vertical section on line 4 4, Fig. 3, looking in the direction of arrow 0, same figure. Fig. 5 corresponds to Fig. 1, but shows my improvements applied to a loom having drop-shuttles, in this instance three banks of shuttles. Fig. 6 is an end view and partial section on line 6 6, Fig. 5, looking in the direction of arrow d, same figure. Fig. 7 is a top view of the lay shown in Fig. 5 looking in the direction of arrow 6, same figure; and Fig. 8 is a detached view of the angle metal ban-taken on line 8 8, Fig. 5.

I will first describe the construction shown in Figs. 1, 2, 3, and 4 of the drawings. In said figures, 1 is the upper part of the laysword, which may be of the ordinary and well-known construction in this class of looms and which is pivotally supported at its lower end, (not shown,) so as to have a pivotal or swinging motion in the ordinary way, and is connected to and operated by the crank-shaft (not shown) in the ordinary way. Two or more lay-swords are employed, according to the width of the loom. The upper part of the lay-sword 1 has upon its upper end at its front side an extension or bracket 1, forming a surface to receive a metal bar 2 of angle shape in cross-section, which forms the laybeam of the loom. The angle metal bar 2 is rigidly secured to the bracket 1' on the upper end of the lay 1, in this instance by bolts 3 through its lower surface and bolts 1 at its rear side. The angle metal bar 2 extends the full width of the loom and forms the laybeam, taking the place of the wooden beam, Which ordinarily forms the laybeam. EX- tending along the front side of the vertical portion of the angle metal bar 2 is a bar 6, which is preferably detaehably and adjustably connected to the vertically-extending portion of the angle metal bar 2 by screws 7 extending through elongated openings 6 in the bar 6 and screwed into the vertical portion of the angle metal bar 2. The upper side of the bar 6 is recessed or cut out to receive the longitudinally-moving rack 8, which is operated in the usual way by straps passing over rolls or sheaves carried on the lay. (Not shown.) The rack 8 engages with and drives a series of pinions 9, and the pinions 9 engage and operate the swivel-shuttles (not shown) to cause them to move in the guides 10 of the guide-blocks 10 in the usual and well-known Way. The guide-blocks 10 are secured at their upper ends by screws 10 to the upper end of vertically-extending stands 11, which are secured at their lower ends by screws 11 to the upper part of the vertically-extending part of the angle metal bar 2. A rail 12, secured to the upper part of the stands 11 by screws 12', extends transversely across the loom and forms a hand-rail. To adjust the vertical position of the bar 6, carrying the rack 8,1 may employ adjusting-screws 13, turning through a threaded hole in the horizontal part of the angle metal bar 2 and hearing at their upper ends against the lower side of the bar 6. In order to adjust the vertical position of the bar 6, the holding-screws 7 are turned out, and after the bar 6 is adjusted they are turned in to secure the bar in its adjusted position. In Figs. 3 and 4 are shown means for adjusting the vertical position of the rack 8 independently of any adjustment of the bar 6, in which it is supported, to regulate the meshing of the teeth of said rack with the teeth of the pinions 9. Said means consists in this instance of an adjusting-screw 14-, turning in a threaded hole in the lower part of the bar 6and hearing at its upper end against a yielding strip 15, which extends under the lower part of the rack 8 and is secured at each end by a screw 15 to the bar 6. (See Fig. By turning the screw 14 in or out the strip 15 is raised or lowered to raise or lower the rack 8, as desired. \Vhen it is desired to remove the rack 8 for any purpose, the screws 7 are removed to allow the bar 6 to drop down, as shown in Fig. 3, the adjusting-screws 13 being also turned down. \Vhen the bar 6 is in its lowered position, as shown in Fig. 3, it may be readily removed from the front of the lay to remove the rack 8, if desired, or for any other purpose.

In Figs. 5, 6, 7, and 8 I have shown my improvements applied to a narrow-ware loom having drop swivel-shuttles, in this instance three banks of swivel-shuttles. In said ligures the same letters of reference are used to designate the same parts shown in Figs. 1, 2, 3, and 4. In addition to said parts the part marked 16 is the operating-rod of the shuttle-rails. l7 and 18 are reciprocating moving racks for the two lower banks of shuttles and are carried in a bar 19, which is secured by screws 19 to the lower ends of the vertieally-moving stands 20. The stands 20 are adapted to have a vertical up or down motion between suitably-arranged guides through the up-and-down motion of the rod 16, and

they have at their upper ends a bar 21, se-

cured thereto by screws 21, which bar carries the rack 22 for the upper set of shuttles. Intermediate the upper bar 21, carrying the rack 22, and the lower bar 19, carrying the racks 17 and 18, are arranged the guideways or tracks 22 for the longitudinally-moving swivel-shuttles. (Not shown.) All of said parts may be of the ordinary and well-known construction. The lower ends 23 of stands 23 are secured to the rear vertical part of the angle metal bar 2, which forms the lay-beam. The stands 23 have secured thereto the transversely-extending bars 24, which support and form guides for the vertically-moving shuttle-racks and other parts.

It will be understood that the details of construction of my improvements may be varied, if desired, and they may be adapted to be applied to narrow-ware looms with one set of swivel-shuttles or to narrow-ware looms with two or more sets of swivel-shuttles arranged in rows or banks. The bar 2, of angle shape in cross-section, is of iron or steel, forming a very rigid bar, which may be termed an angle-iron.

I have shown in the drawings and described herein my improvements applied to narrowware looms; but it will be understood that I do not-limit myimprovements to narrow-ware or ribbon looms, as they may be adapted to be used on other classes of looms.

Having thus described my invention, what 'I claim as new, and desire to secure by Letters 3. In a loom, the combination with an angle metal bar forming the lay-beam, of a bar detachably and adjustably attached to the vertical portion thereof, to form a way for a reciprocating rack, and said way and reciprocating rack, and means for adjusting the vertical position of said bar, substantially as shown and described.

4.
